New cultivars of non-hardy or interior landscape type (house plants, tropicals, conservatory vines, less hardy bulbs, aroids, non-hardy ferns, bromeliads, cacti, succulents, palms, selected bedding annuals, Begonia, Coleus, and more) are being registered through the new online Hatch's Interior Plants (HIP) enyclopedia now offered as an ad-supported and Patreon-funded content free to the general public. New cultivars and new cultivar groups are being posted in the files with the existing material for a tight, integrated, and uniform presentation under each species.

New for December 2019 is the International Registerof Coleus Cultivars, now free in the public interest from the
International Coleus Society (ICS). This reference has over 1600 cultivars described and with illustrations and high-res images when possible. These cultivars were introduced from 1858 to 2020. The ICS has been concerned that some names are being applied in commerce and among collectors for 2-4 different clonal and seed strain entities, causing more confusion. Some trademark names are also the same epithet(s) as existing, established cultivar names, adding even more chaos. Besides trying to sort out the various origins of clones and names, the ICS wants this document to discourage future homonyms in the trade. In other words, "that name is taken...let me pick a better one". If you wish to support this project please join the ICS or subscribe to any of the Cultivar.org Encyclopedia. The ICS has more than 10 advanced, members only projects you can join including visual analytics, cultivar ID, landscape practice, phyllometric taxonomy, cultivar history studies, breeding and genetics, germplasm conservation, Coleus Art, and Cultivar Groups.

Effective 1 January 2020 OROC cultivar registrations will be published once per year as in the categories of woody plants, hardy herbaceous perennials, and interior and tropical plants with all genera in one volume. As always these will be in PDF format and 100% free to download and share under OROC Data Sharing rules.
The next free volume is slated for Spring 2020. For more frequent updates, our Cultivar Encyclopedia subscribers (who fund 90% of OROC) can receive frequent updates, as often as once a week, at no additional charge through a link on their menu pages. This new program is called OROC+NOW and is similar to the "working registers" seen in the past, showing additions as they come to us with only the least bit of delay for verification. This is our way of rewarding our absolutely necessary and loyal sponsors and also motivating new plant developers to share data with a rich marketing base to a virtual "Who's Who" in ornamental horticulture and many thousands of revoted collectors, growers, and curators with real buying power. It's new...we want it NOW!

of distinguished botanical and horticultural monographs and studies
Bean's Trees and Shrubs Hardy in the British Isles
The British master himself and one of the most
influential woody plant guides in history. It
took me 10 years and about $150.00 to
find all the volumes on this shore. Now it's free.
Hibberd's New and Beauitful Leaved Plants
One of the mostly lovely plant books
ever printed. Stunning images and expert
commentary. Hibberd adored variegation.
Wilson's A Monograph of Azaleas
From the collector of many taxa himself,
this is splendid reading for even the
most experienced lover of the genus
Carriere's Trait General des Coniferes
One of the classic, core conifer books of the last two centuries. It's
amazing how many modern popular conifers this man named. Ever
see Carr. after a name? That's him.
Sudworth's Nomenclatural of the Arborescent Flora of the United States
I regard Sudworth as perhaps America's first great woody plant taxonomist. This is a stunning catalog not just of species, their synonyms,
common names, but also numerous cultivated varieties
Bailey's The Nursery Book
This was one of the most widely distributed nursery guides in the US and from the great one himself. I've always liked calling propagation by his terms of seedage, cuttage, and graftage. It seems so proper and academic.Bailey invented the word "cultivar" and conspired to be a "horto-botanical" writer, meaning that both horticulture and botany were blended into the whole. By the way he did all this while Dean of the College of Agriculture at the Ivy League Cornell University.

The Internet Nursery Catalog Archive (INCA) is a massive archive of digitized or saved nursery catalogs from 2000 to present. It is kept by Cultivar.org for research purposes and because nearly all the material is subject to copyright, it can be shared online. Portions of it are available on request to researchers with a direct need to material that be offline and especially from closed nurseries and gardens. More than 41% of INCA content is no longer online, making these resources extremely valuable to cultivar, garden, and nursery history researchers. Remembers all those nurseries than went out of business some years back? If they did ornamental cultivar work, we probably have a catalog or ten or portions of new cultivar features.
Since 2005, we decided it made INCA a more versatile, "all purpose" archive for digital research materials and it now includes PDF academic articles, JPG images of new plants, screen captures of important websites, plant identification keys, digitals floras, plant collection lists, garden maps, cultivar registers, plant databases, cultivar release notices, old nursery catalog PDF, horticultural monographs, videos of ornamentals related presentations, scanned articles, and much more. A simple search by genus or species usually produces scores if not a hundred documents which may or may not still be on the web; and now many never were there.
INCA is a major part of our research for cultivar documentation, especially when revising a genus for the Cultivar Encyclopedia. Researchers often send us material to archive for them as we distribute INCA informally to several reliable libraries and partners for safe keeping.
If you have a very specific research project, write us: ornamentals (at ) lycos.com and we will list what resources we have. Graduate students, professors, and independent researchers are welcome to contact us. Typically we send a thumbdrive full of files but smaller requests are send by regular email channels.

Hatch's Perennials 2018-2020 Edition
You receive all updates through December 31, 2020
This is the latest version as of August 20, 2018
Here's what you get:
- MORE DATA: more cultivars than everywhere else, more than 4100 PDF 8x10 in. pages and over 380 megabytes. No print publisher would every comprehend sending out this much information. This is only doable and affordable as digital ebooks.
- AUTHORITATIVE: Horticultural taxonomist Larry Hatch (BS Cornell, MS NC State) has worked on this and collected perennials for more than 35 years and had more than two decades of expert advice from the New Ornamentals Society.
- VERSATILE: you can put the entire system on your phone, tablet, laptop, desktop, ebook reader, and other device - anything that reads PDF files. More than 480 devices are supported.
- EVERYWHERE YOU GO: you have this data wherever you carry your devices in the garden, nursery, botanical garden, classroom, lab, or your client's office.
- YOU OWN IT FOREVER IN SECURE DIGITAL FORM: If you download the PDF files on your own devices, you have them forever as long as you keep the password (please do). If you decide to purchase updates from our 2018 and future editions, it's up to you to decide when and if you do.
- ORIGINAL AND EXCLUSIVE: unlike some popular perennial books this is not a crude "compilation" with the pooled ignorance of random interest users unfiltered by experts. HP2016-17 contains decades of original real garden, literature, nursery catalog, and plant trials research. Thousands of observations and data points are exclusive.
- FREE UPDATES: does your old perennial book author and publishers send you free updates and supplements every month or so? We're guessing...no! We will. You get all the new data and updated files through December 2020 at no extra charge. Your subscription lasts that long.
- CULTIVAR SPECIFIC DATA: we are very detailed on individual cultivar heights, habit, color, origins, history, leaf traits, and more.
- AMAZING, SCREEN-WIDE HIGH-RES IMAGES: from the very beginning Mr. Hatch insisted we publish huge 900 pixel wide images with clarity and lots of digital SLR detail. He even told nurseries and breeders their promotional images were frankly cr@p and modern public relations and scientific documentation (both) deserved better. Today our standard is 1250 pixels wide. No print book publisher could give hundreds of these big, ultra high quality pictures for less than hundreds of dollars in coffee table type books. We do...starting at just $59.00
- OROC SUPPORT: not only does this work plug into all the new perennial cultivar registrations of the Open Registration of Cultivars project but you subscription directly funds that project. There is absolutely no other organization actively and assertively cataloging new hardy plant cultivars with peer-reviewed standards.
- ACADEMIC, SCIENTIFIC QUALITY: we include literature citations, university cultivar release notices, expert trial reports, screen prints of classic old catalogs and literature, identification tips, taxonomic notes about related formae, varieties, and subspecies.
- NO SHIPPING OR CURRENCY CONVERSION COSTS: with our digital delivery you save on handling, packaging, and postal costs. We can't do anything about local taxes. Currency conversion from over 100 countries is usually free and in the old days that could add $8-30 to our orders. Occasionally we pay 30-70 cents and we "eat that" with no worries.
- YOUR FEEDBACK MATTERS: Mr. Hatch insists on personally receiving and taking action with permission on submissions from all users, including your own new cultivars, images, your observations, comments, corrections, and anything else you can to share. Hundreds of past readers of Hatch's Perennials have sent images and new cultivar descriptions as well as interesting plant histories that became part of this worldwide, shared resource.
You will receive a download website page address/URL and password by email, usually within 48 hours of your order, to access your new resource. THIS IS NOT A PRINTED BOOK and we do not mail any content. This is a 100% digital service.
- If for any reason Paypal decides to delay, hold, or verify your order, we are required to delay this information until the payment is confirmed. We may not be paid if you have any existing holds or "open cases" with Paypal. Write us at ornamentals@lycos.com if you need to pay by another method.
- If
you Paypal email address is outdated we will have no way to reach
you. Please update that website or send your order data to
ornamentals@lycos.com with the correct address without delay.
